I'E'E(fH'ICAJHIOIAT formingpart of Letters Patent No. 781,506, dated.January 31, 1905 Application filed No ember 11, 1902. Serial No.130,897.

of raw resin takes place, causes considerable loss of product, and mayrender the resulting sizing unfit for use.

The. present invention now has for its object a process by means ofwhich resin soap with an admixture of as high as one hundred per cent.free resin can readily be emulsified in hot water. The resuitis a resinsoap of a very high percentage of free resin and of correspondingly goodgluing properties, also a great saving in alum.

.The accompanying drawing is a side elevation of the apparatus employedin my im proved process.

In carrying out the invention the resin soap is heated in a suitablereceptacle 1 by means of steam-coil 2 or some other appropriate sourceof heat and is then conducted through the connection 3 intoa'measuring-receptacle i, where it is still further heated by asteamcoil .5 or the like. On its further way to the receptacle 6,wherein the emulsifying operation is to take place, the heated resinsoap passes through a steam and water mixing device 7, preferably of theinjector type, said mixing device or injector being adapted to receivesteam through the steam-supply pipe 8. By the steam entering thesolution within this mixer or injector the temperature of the resin soapand water solution is still further enhanced, so that the finaltemperature of about 212 Fahrenheit is obtained. The heated resin soapand water solution is then atomized by means of the steam-pressurebehind it within the mixing device, injected into the lime-watercontained in the emulsion-vat, and emulsified therein. The water used inthe mixer is preferably taken from the emulsion-vat 6 by means of a pipe9, connected to the mixer or injector and in communication with the vat,the supply of water being steadily fed to the vat by a supply-pipe 10for the purposeof keeping up active agitation, thereby aiding theemulsifying process. The result .of the described process is anon-settling sizing, which is next conducted into the reservoirs, fromwhere it is run 0H into the rag-engine.

In place of the steam-injector I may see fit to employ a suitableforce-pump or the like.

Although I have described my new process.

only in the treatment of resin soap, it is ob vious that also otherproducts which can be emulsified may be treated in this manner. and inplace of limewater other liquids, such as oil or the like, may be used.

What I claim, and" desire to secureby Letters Patent, is.

Process for emulsifying resin soap in water, consisting in heating resinsoap, mixing it with waterunder steam-pressure and injecting the heatedmixture in atomized state into limewater, for the purpose of bringingabout perfeet emulsion, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
